that is really strange Iare - I hope you believe me, when I am telling you that this is not a general problem of GPSLogger - there are many many happy users that even create logs for days (the max. I have seen so far was 8 days long)...

Something that might be possible is, that you are running out of memory while you are recording you log -> could you just make a quick check and tell me how many free ram you have available? [but this is just a wild guess - since you say that it also happens, when you switch the task by accident... I really seams to be clueless for now - mhhh - looks like I need some "FileScout-free days"]
